Non-partisan, independent presentation of climate data. No political ideology, agenda, or financial incentive. Just the data and the trends from published peer-reviewed research, no matter what it shows. We don't cherry pick. Site owner is a Ph.D. geologist who attempts to present the data in as simple a format as possible, so everyone can understand. Choose a subject from the list, or just scroll down. Data is presented in at-a-glance format with minimal analysis. Climate change is much more than just temperatures.

We don't post often, as there is no need to repost the same data over and over. But we do post data from scientists who have boots on the ground and are doing the dirty fieldwork to collect data.

Global Average Temperature Reconstructions

The most famous temperature reconstruction graph is that done by Mann, 1999. But there are many other, independent reconstructions:


A quick note about the Medieval Warm Period. Temperatures around 1000AD were at similar levels to today in northern Europe across to Greenland. Recent data indicates that the MWP was a local phenomena and mostly confined to that region, rather than a global temperature increase. Current temperature reconstructions from other parts of the globe show no such warming.
